Sealing System  For Sealing of a Drain Arrangement

ABSTRACT

Sealing device ( 1 ) for sealing a drainage arrangement, including a flexible sealing film ( 3 ) with an opening ( 4 ), through which waste water can pass, and a connecting portion that is connected with the sealing foil ( 3 ) and that can be connected with a portion of the drainage arrangement.

The present invention relates to sealing devices for sealing a drainage arrangement, a drainage arrangement for at least partial installation in the floor of an area with such sealing devices and a drainage device for draining water from an area with such a drainage arrangement.

Sealing devices, a drainage arrangement and a drainage device of the aforementioned type are known from EP 2 423 395 A1. In the drainage arrangement described therein, a rubber ring of the sealing device acting as a support is introduced into the opening of the drain opening of the drainage body and retained therein in particular by the drain port of the water collection device, which are constructed as a drainage channel.

Disadvantageously, the rubber ring can be compromised, for example displaced, as a result of the insertion and adjustment of the drain port, thus preventing a sealing action. Moreover, odor traps disposed in the drain opening can no longer be displaced at a later time.

The problem which is addressed by the present invention is the creation of sealing devices, of a drainage arrangement and of a drainage device of the aforementioned type that can be more flexibly adapted to different local requirements and/or that can provide a more reliable seal.

This is achieved by the sealing devices according to claim 1, by the drainage arrangement according to claim 6 and by the drainage device according to claim 10. The dependent claims are directed to preferred embodiments of the invention.

Particularly advantageous is a design where the groove surrounds the opening and is at least partially spaced apart from the opening, so that a gap for supporting the seal is created between the opening and the groove which encircles the opening. This gap can be used, for example, to displace a portion of water collection devices placed on top of the drainage housing. The displacement allows adaptation to local situations.

Furthermore, an odor trap insert and a shuttle frame for the odor trap insert can be arranged in the gap between the groove and the opening. The shuttle frame avows the odor trap to be placed at different positions, thus also facilitating adaptation to the local situation.

Furthermore, arranging the support of the seal outside the opening enhances the reliability of the seal, in particular, because the sealing device is not contacted when a connecting piece is inserted in the opening or when the odor trap is inserted and removed.

Further features and advantages of the present invention will become apparent from the following description of preferred exemplary embodiments with reference to the appended drawings, which show in:

FIG. 1 to FIG. 10 cross-sections through a drainage device according to the invention with a water collecting device designed as a drainage channel;

FIG. 11 to FIG. 18 cross-sections through a drainage device according to the invention with a water collecting device designed as a drainage profile;

FIG. 19 to FIG. 24 cross-sections through and plan views of a drainage device according to the invention with sealing devices according to the invention.

In the figures, identical and functionally identical parts are provided with identical reference numerals.

FIG. 23 and FIG. 24 show a sealing device 1 according to the invention before attachment to a drainage body 2 of a drainage arrangement according to the invention. The sealing device 1 has a waterproof sealing film 3, which can be composed of different types of plastics. The sealing film 3 has an, in particular rectangular, opening 4 (see FIG. 24), through which water can flow to the drainage body 2.

A support 5, which has on its side facing the opening 4 a circumferential seal 6, in particular a lip seal, is attached at the bottom side of the sealing film 3. The support 5 may be constructed of a hard plastic such as PP. The seal 6 may be constructed of a soft plastic such as TPE.

The drainage body 2 is constructed as drainage housing with a housing cover 7 which also has an, in particular rectangular (see Fig, 24), opening 9. The support 5 with the seal 6 can be inserted, preferably snapped or clipped, into a circumferential groove 8 of housing cover. A gap 10, which can be used, for example, to displace a portion of the water collecting device (see, for example, the substructure frame in Fig, 3 and Fig, 4) disposed on top of the drainage housing, remains between the groove 8 and the opening 9.

Furthermore, an odor trap 11 and a shuttle frame 12 for the odor trap 11 are arranged in the gap 10 between the groove 8 and the opening 9.

When the drainage arrangement is installed, a composite seal is applied on the sealing film 3, onto which in turn tiles can be placed.

FIGS. 1 to 10 show a drainage channel as the water collection device, With this approach, a lateral compensation of the substructure frame within the sealing device 1 or in the gap 10 is possible perpendicular and parallel to the wall.

FIGS. 11 to 18 show a drainage profile as the water collection device. With this approach, a lateral compensation of the profile is possible on and within the sealing device and the composite seal arranged above, or in the gap 10 perpendicular and parallel to the wall.
